Thanks! I had a similar issue - the log file was not getting reused even though the recovery mode was set to SIMPLE, and the log_reuse_wait_desc reason showed 'replication' even though there was no replication set up for the db (verified thru DATABASEPROPERTYEX ( db_name() , 'IsPublished' ), which returned 0). To resolve the problem, I tried "sp_repldone null, null, 0,0,1" first, but that just gave an error message that the db is not marked as being published. Then tried sp_removedbreplication, and that worked like a charm.
